Enertopia Announces Water Producing System for PV Panel Patent Issuance from USPTO

Rhea-AI Summary

Enertopia (OTCQB: ENRT) has received USPTO patent #12231085 for its water-producing system, trademarked as the 'ENERTOPIA RAINMAKER'. The system captures atmospheric moisture using PV panels, capable of producing 2.45 to 4+ gallons of water per hour for every 80" x 40" panel during peak conditions.

The technology presents an alternative to traditional desalination plants, which require significant capital expenditure ($1,000-$2,500 per cubic meter daily capacity) and operational costs. Testing data from various locations shows promising results, with maximum production capabilities ranging from 5,288 to 10,376 gallons per hour per MW of solar array, depending on location.

The system is particularly effective in arid coastal and monsoonal areas where dew points are close to ambient air temperatures. It can operate during different times of day and atmospheric conditions, with PV power generation during daylight hours and water production at night.

Positive

Kelowna, British Columbia--(Newsfile Corp. - February 18, 2025) - Enertopia Corporation (OTCQB: ENRT) (CSE: ENRT) ("Enertopia'' or the "Company") an energy company focused on building shareholder value through a combination of our intellectual property patents in the green technology space, along with our Nevada lithium claims, is very pleased to provide the following Patent update.

Water Producing System Patent Issued - #12231085

The United States Patent Trademark Office (USPTO) has notified the Company that patent number 12231085 was issued today, February 18, 2025. This system has also been Trademarked as the "ENERTOPIA RAINMAKER".

The ENERTOPIA RAINMAKER can be used during different times of day and atmospheric conditions to capture the moisture (water vapor) in the atmosphere.

Our analysis shows that depending on time and place during the year, key locations in the world are potentially capable of producing 2.45 gallons to over 4 gallons of water per hour for every 80" x 40" PV panel, during peak atmospheric conditions as seen in Table 1 below.

The Current Problem:

In many arid regions of the world desalination plants are a major source of freshwater. Abu Dhabi, U.A.E. for example, uses them to produce approximately 42% of its freshwater, and the majority of its drinking water. Due to lack of freshwater sources, it is important for the UAE, and other similarly arid regions, to identify a sustainable desalination solution to meet long-term water needs.

While desalination plants are effective, they are extremely expensive to build with capital expenditures (CAPEX) running between $1,000 to $2,500 per one cubic meter of water per day m³/d, which equals 264 gallons of capacity. (OPEX) cost depending on the size of the desalination plant can run from 50 cents for a large 2,500 per m²/d to a 500 per m²/d $2.50 cents. And these costs do not include the cost of fuel running many of the bigger projects in the world. Thus desalination plants are only for the few locations that have the capital and source of cheap fuel and can afford to spend billions of dollars to build the plants. Thus thousands of locations and millions of people have had no opportunity for reliable water.

Enertopia's Patented Solution:

Desalination plants use a tremendous amount of energy to produce freshwater, 1,510 Mega Watts (MW) of electricity to produce 100 Million Imperial Gallons (MIGD) of water per day. This energy demand is equivalent to nearly two large scale nuclear plants. Most world governments simply cannot afford to spend billions of dollars and take a decade to build projects that are needed now for a better quality of life. The Enertopia Rainmaker could be coupled with solar arrays where efficient PV power will be produced by day, and water produced by night, and seasonally even during the day.

Enertopia believes that this approach will significantly increase the ROI of any power project where water shortages exist. Arid coastal and seasonally monsoonal areas are particularly favorable for water production as the dew point can be close to the ambient air temperature making it easier to cool down the PV panel and capture the moisture. Due to the scalability of this system it could also work for smaller projects in remote locations with no water or power, and who rely on the trucking or flying in supplies.

Worldwide Potential

Table 1 below uses the data from four locations. Tonopah, NV which is the location of our West Tonopah Lithium project, is where the data for the first row of column 1 is generated. We were able to show that at maximum production, there is the ability to extract as many as 5,466 gallons of water per hour/MW of solar array. The varying factors in the data are; humidity levels, ambient air temperature, and dew point. Column 2 shows the average water extraction per hour/MW of solar array.

The raw data (humidity levels, air temperature, & dew point) used for each location in the table can be found below in the notes.

Generally, moisture that exists in air is measured as grains of moisture per pound of dry air. At the point of saturation (e.g., dew point), water forms on cool surfaces. This process generally occurs at night. During the heat of the day, as ambient hot air pulls moisture from surrounding environments, moisture will also form on cool surfaces, with our heat recovery system taking advantage of these conditions to collect and retain the moisture formed at dew point temperatures.

The moisture collection layer is positioned between the photovoltaic panel and the liquid transfer system to facilitate the rapid transfer of heat from the photovoltaic panel to the liquid transfer system. In some instances, during periods when, due to surrounding ambient conditions, moisture will not naturally form, the heat recovery system described herein may employ a controlled water emitting means to ensure saturation of the moisture collection layer.

"We look forward to the next steps of solving real world energy and water problems," states President Robert McAllister
